Water Heater Installation
Condensate Drain Installation
Installation must conform with these instructions and local building codes.
Field supplied materials required for installation include:
•Approved PVC cement and PVC primer.
•1/2 inch PVC pipe - minimum length to equal the distance between the water heater and a suitable building drain.
•1/2 inch PVC fittings (elbows and couplings) necessary to install a condensate drain line between the Condensate Drain Trap Assembly and a suitable building drain.
•Floor mounted standoffs to brace the drain line.
Installation Notes
1.The condensate drains from the water heater’s covered by this instruction have PH levels between 4.3 and 5.0. Install a commercially available neutralizing kit if required by local codes. Lower PH levels are acidic. Do not connect a metal condensate drain line, such as copper pipe, to the water heater for this reason.
2.The field installed condensate drain line must not be less
than 1/2 inch PVC in size.
3.Do not remove, modify or alter the factory condensate trap.
Installation Instructions
1.Ensure the water heater’s on/off switch is in the “off” position.
2.Install a 1/2 inch PVC condensate drain line between the condensate drain connection on the Condensate Drain Trap and a suitable building drain, see Figure 50 and Figure 51.
3.Terminate the condensate drain piping with an elbow above the drain. Ensure that any discharge will exit the condensate drain line no more than 6 inches (15.2 cm) above a suitable building drain, or external to the building, see Figure 50.
Note: In cold climates it is recommended the condensate drain be terminated at a suitable drain inside the building.
4.Ensure the condensate drain line is not elevated above the condensate drain connection on the trap, see Figure 51.
5.Brace the condensate drain line with floor mounted standoffs every three feet.
6.Ensure the condensate drains freely during start up, see
Start Up on page 52.
